JOSEPH STOPPELKAMP, OF ST. LOUIS, MISSOURI.

FRUlT-STRAINER.

SPECIFICATION forming part of Letters Patent No. 424,907, dated April 1, 1890.

Application filed October 25, 1889. Serial No. 328,121. (No model.) I

To all whom it may concern.-

Be it known that I, JOSEPH STOPPELKAMP, of the city of St. Louis, in the State of Missouri,have invented a certain new and useful Improvement in Fruit-Strainers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to an improved apparatus for expressing the juice from small fruitssuch as grapes, cherries, currants, 850.; and my invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Referring to the drawings, Figure I is a perspective view of my improved strainer. Fig. II is a vertical section taken on line II 11, Fig. III. Fig. III is a vertical section taken on line III III, Fig. II. Fig. IV is a longitudinal view of one form of roller that I prefer to use in my apparatus, and Fig. V is a detail view of a portion of the straining-plate.

The vessel in which the fruit is placed has end boards 1, provided with legs 2, in which the grain of the wood is shown vertical, and attached to their sides are wooden pieces 3, whose upper edges are flush with the upper edges of the pieces or boards 1, and whose lower edges 4 are semicircular for the attachment thereto of the edges of the strainer sheet or gauze 5. It-is preferred that the strainer should be of perforate metal; but gauze or wire-work may be used, if preferred, as it might be for some purposes. The upper edges of the strainer are held between the longitudinal strips 6,secured to the vertical edges of the ends 1 3 and interior angular battens or cleats 7, which act not only to cover and hold the upper edges of the strainer, but also to prevent by their sloping under faces '7 the contents of the vessel from being splashed out, for it will be seen that the shape of the cleat is such that any material passing up the strainer would be deflected inward as soon as it reached the cleat. It is preferred that the grain 'of the parts 1 and 3 should cross each other, and for this purpose the grain in the piece 3 may be horizontal, as shown.

At 8 are oblique channels extending from the upper edges of the parts or pieces to cillated. At the lower part of the side pieces are recesses 14, which receive the ends and form the bearings of the loose mashing-rollers 15. Said rollers are shown cylindrical from end to end and restrained from en dwise movement by the end pieces 3 of the box or vessel.

\Vhere the fruit is hard, a circumferentiallygrooved roller 15 may be substituted for the central one of the cylindrical rollers. This grooved roller is shown in Fig. IV.

16 is a bar whose ends have support in the side pieces 11. From the bar 16 extend mixing pins or studs 17, which may be placed in a vertical downwardly-extending position, as shown, when it is desired to stir the mass of material, or which may be made to project upwardby turning the bar, as seen in dotted lines in Fig. III, when the material does not require their action. The bar 16 is held in whichever position it may be placed by a hook 18,which engages in holes 18 in the opposite sides of the bar 16. In order to hold the ends of the fulcrum-bar at the points 9, screws 19 are passed through the side pieces 1 into the ends of the bar.

I claim as my invention- 1. The combination of the vessel, the curved strainer, the fulcrum-bar secured across the vessel to the sides of the same, the frame oscillating on the fulcrum bar having recesses,

and the roller whose ends occupy the recesses, substantially as and for the purpose set forth.

2. In a fruit-strainer, the combination of the vessel, the curved strainer, the fulcrum-bar secured across the vessel to the sides of the same, the frame oscillating on the fulcrum bar having recesses, and the series of rollers whose ends occupy the recesses, substantially as and for the purpose set forth.

IOC

In a fruit-strainer, the combination of the end boards 1, the pieces 3,having lower seinicircular edges 4: and formed with channels 8, the curved strainer, the longitudinal strips 6, the fulcrum-bar 10, the frame oscillating, on the fulcrum-bar, having side pieces 11, formed with recesses ll, and the mashing-rollers 15, snbstanti ally as and for the purpose set forth.
